Abstract
An arrangement is provided where a media server temporarily stores a DRM license that is associated with downloaded media content prior to copying the DRM license to a physical archival medium such as an optical disc. When the media server confirms that the DRM license is successfully copied to the physical archival medium, it destroys the temporarily stored DRM license.
Claims12
A system comprising:
- one or more processors in an electronic device;
- a memory, the memory including computer-executable instructions which, when executed by the one or more processors in an electronic device, cause the one or more processors in an electronic device to perform the steps of:
- confirming receipt of a DRM license associated with downloaded media content at a temporary storage location, the temporary storage location within a server as part of a Hard Disk Drive (HDD) of the electronic device;
- confirming that the DRM license is copied to a removable physical archiving medium;
- and
- wiping the DRM license written to the temporary storage location so that the DRM license written to the temporary storage location is not restorable in any way, after confirming that the DRM license is copied to the removable physical archiving medium, to thereby permanently erase the DRM license from the temporary storage location.
